Automotive-grade TVS for 20V rails
The SMAJ20CAQ-13-F: Its 20V reverse standoff voltage (V_RWM) means it sits across a 20V nominal rail without conducting leakage, clamping at 32.4V max when the pulse current hits 12.3A. The DO-214AC (SMA) package is a standard surface-mount footprint for TVS diodes; the bidirectional single-channel configuration eliminates orientation concerns during pick-and-place.
Active production, no successor watch needed
The base product number is SMAJ20; the -13-F suffix denotes tape-and-reel packaging with full reel quantity.
